If you already have an Xbox with entirely digital games then I’d say yes. If you either have the vast majority physical or don’t have one then I’d say that unless you only plan on playing a handful of games that you are better saving up and getting a series X. I say this as a lot of the games on the Xbox store are still a lot more than what you can find used or even new for a lot of physical games.

TLDR

If you have a lot of digital games/aren’t going to play many games then YES

If you either have a lot of physical games or are going to buy a lot of games then save and get a series X
